Letters Patent No. 99,954, dated Februar/rg 15, 1870.

*Mai- HEATING STOVE.

The Schedule referred to in these Letters Patent making part ofthe same.

I, WILLIAM Fnkzrnn Ross, of Davenport, in the county of Scott, and State of Iowa, have invented certain Improvements in Stoves and Fire-Places generally, of which the following is a. specification. l

Nature and Objects of the Invention.

The first part of my inventio1i-,relates to the combination with a stove or other fire-place, ofa siphonic air-duct, in such a manner that the air fol-the support of combustion may be taken from the room near the door and discharged over the lire, so that the gas and smoke may not be released more rapidly than they are consumed, and so that they may not escape through the same channel into the room; the objects of this part of my invention being to equalize the temperature of and ventilate. the room, and to thoroughly consume the gas, smoke, and fuel.

The second part of my invention relates to the combination with the inside. leg ofthe siphobic air-duct, of a fuel-box, one side of which is open at the bottoni, in such 'manner that the cold air may he drawn down through the fuel and retard its colnbustion above the opening at the bottom, drivingr the heat through said opening; ,and to the combination of dampers with apertures, inthe saine side ofthe fuel-box in such manner that an increased quantity of fuel inlay he ignited by opening one or more ot' the dampersand allowing a portion of the-draft to pass through one or more of the apertures, and so that the apertures and damper-s may not be obstructed by the fuel.

The third part of my invention relates to the combination with the fire-box and an air-tight ash-box under it, of an air-tight sliding bottom tothe lire-box,

which may be opened suiiiciently to allow the ashes and clinker to drop into the ash-box, and which may be closed when the ash-box is open, and so prevent `air from passing up through the tire and fuel and releasing gas and smoke more rapidly than they can be consumed.

Description of the Accompanying Drawings.

Figure 7 is a vertical transverse section4 of l a cooking stove embodying my invention.

Figure 2 is a like section ofa warming stove embodying the saine.

Figure 3 is a horizontal section of that part of a stove which embodies my invention.

General Description..

A is the outside leg of thesiphonic air-duct, which* feed of the fuel, and prevents its ignition, until,A by

the consumption at the bottom, it is allowed to drop into the lire below the level ofthe aperture where the upward draft is allowed to have vent.

The aperture D is made by setting the under part of the side-of the fuel-box C' farther ont than the upper O, so that the aperture and the damper over it may not beobstructed'by the fuel.

-E is the fire-place.

F is the vent for the draft.

G is an air-tight sliding bottom under theiire-box E, which may, by the rodph, be opened suoiently to allow the ashes and clinkers drop into the ash-box I, and'which is to be kept closed when the ash-box I is open.

I is' an ash-box with a drawer, closing air-tigl'it, for reoeivingand holding the ashes and clinkers as they are precipitated from the fire. y

M is a door at the top of the fuel-box B, where the lire and fuel are introduced.

Mode of Operation. l

Place the fire at the bottom of the fuel-bozlzvB and under the side C G'. The iue1-box may be filled with bituminous coal or other fuel, which will, when the danipers D and D and the ,sliding bottoni G are closed, burn only below the-level of the bottom of the side C Cf or where it is'started. The door M should be kept closed except when opened for the introduction of lire, or fuel. y,

l The sliding bottom G may be opened as required,

to let the ashes and clinkers drop into the ash-box I,. .whielrniust meanwhile be kept closed. Before remov-A ing the drawer I, the sliding bottom G of the fire-box, must beclosed by means of the rod h..

More fuel may be ignited by opening the damper D', and all in the fuel-box by opening the damper D.

The draft may be regulated by a damper, t, in the outsideleg of the siphonic air-duet A.

Claims.

. I claim as my inventionl ,Y

1. The combination of the siphonicair-duct A B with a stove or other fire-place, substantially as and for the purposes herein before set forth.

2. The combination with the inside leg of the siphonie air-duct, ofv the fuel-box B, with the side O C', and the combination of dampers D DA', with apertures, in the side -of the fuel-box, substantially as and for the purposes herein before set forth.

. 3. rIhe combination with the fire-box E- and airtight ash-box I, of the air-tight sliding bottom G, substantially as and for the purposes herein before set forth.
